Fine Jewelry Designer Janet Deleuse began working in the family jewelry business following her marriage to gemologist Jeff Deleuse. She put a degree in molecular biology aside to embrace her true passion for art and design, which she had cultivated since childhood.

By 1982, her love of the hand processes in creating artwork had blossomed into designing magnificent, one-of-a-kind statement jewelry—earrings, bracelets, necklaces, rings—that have been featured in WWD, Town & Country, The Robb Report and Lustre Magazines, among others.

The designer's exclusive hand fabricated pieces are widely recognized for classic lines and fine quality gems, including pearls and flawless WS, VS and EF diamonds set in 18k gold or platinum, as well a penchant for monochromatic styling—"I like clean lines, says Deleuse, even if the design is intricate."

In addition, the designer has recently expanded into couture outerwear and accessories with a collection of pearl evening bags, pearl belts, silk scarves and couture outerwear, all handcrafted in the San Francisco Bay area and offered under the Janet Deleuse label.

Family owned and operated Deleuse Jewelers was established in 1934 by John Deleuse, a master watchmaker and graduate of the Ecole Nationale d'Horologie de Cluses. In 1945, he opened the first family-owned and operated boutique in his hometown of Nice, France.

Janet and Jeff Deleuse opened Deleuse Jewelers in Fairfax, California in 1982, and continue the brand's mission to offer the most uniquely elegant jewelry, using the worlds finest gems and employing the highest quality craftsmanship.

Janet Deleuse is an accepted member of the Contemporary Jewelry Design Group, a national organization dedicated to the promotion of creative jewelry design and committed to the highest standards of integrity and ethics in business and design.

"My wife had Deleuse make her a new ring using the diamonds from her engagement/wedding rings and her mother's ring. The new ring is absolutely beautiful and turned out exactly how we were hoping. Jeff was very helpful in the design phase, listening to our ideas and showing us what would and wouldn't work. His skill is evident in the finished product. We couldn't be happier. Both he and his wife very pleasant to work with." Charles C., Fairfax, CA12/16/2017

The knowledge and service is wonderful, nothing is too much trouble for them...." Chrissie, Livermore, CA

"This store has a very pleasant environment and Jeff and Janet are both kind, wonderful people. I used Jeff a few times for appraisals and he was very thorough and was happy to answer lots of questions. He uses scientific methods and tests rather than going solely by appearance as some jewelers will try to do, and his expertise is well respected. On one occasion, he even went out of his way to help expedite a deal for me. He has my highest recommendation. Suzanne T., San Rafael, CA

"Janet & Jeff designed our wedding rings 5 years ago and I went back to them for another ring for my wife. Excellent design and excellent quality diamonds and aqua marine.

"I'm on a Pink Pearl Cloud, I am in love with my new pink freshwater pearl necklace! It has a high luster and a slightly grey color tone. It reminds me of a color I once read about called Ashes of Roses. I feel that the pink/grey tone will lend itself to coordinating the pearls with a greater variety of clothing colors than if they were strictly pink. I think that they were quite reasonably priced and look forward to wearing them frequently!"
